Do you think his jealous behavior means he likes me?

I am crazy about a guy named Jake. We hook up but Jake said he does not want a girlfriend. Although I know Jake is attracted to me- he often acts disinterested and aloof towards me. The other night at the bar, a hot guy named Anthony, that Jake and I both know had begun hitting on me in front of Jake. We then began to kiss in front of Jake. To my surprise, Jake got up from his seat and went crazy trying to break us up on the down low. He started acting all jealous. Jake followed me around the bar like a sick puppy dog. Do you think this MOST LIKELY means that deep down Jake has some kind of liking/affection for me? Or do you think his behavior was primarily about his self-esteem and ego, and nothing to do with me really.
